FIELD OF THE INVENTION

The present invention relates to fused cyclic compounds, to methods ofusing such compounds in the treatment of nuclear hormonereceptor-associated conditions such as cancer, and to pharmaceuticalcompositions containing such compounds.

BACKGROUND OF THE INVENTION

Nuclear hormone receptors (NHR's) constitute a large super-family ofligand-dependent and sequence-specific transcription factors. Members ofthis family influence transcription either directly, through specificbinding to the promoter target genes (Evans, in Science 240: 889-895(1988)), or indirectly, via protein-protein interactions with othertranscription factors (Jonat et al., Cell 62: 1189-1204 (1990), Schueleet al., Cell 62: 1217-1226 (1990), and Yang-Yen et al., Cell 62:1205-1215 (1990)). The nuclear hormone receptor super-family (also knownin the art as the “steroid/thyroid hormone receptor super-family”)includes receptors for a variety of hydrophobic ligands, includingcortisol, aldosterone, estrogen, progesterone, testosterone, vitamineD3, thyroid hormone and retinoic acid (Evans, 1988, supra). In additionto these conventional nuclear hormone receptors, the super familycontains a number of proteins that have no known ligands, termed orphannuclear hormone receptors (Mangelsdorf et al., Cell 83: 835-839 (1995),O'Malley et al., Mol. Endocrinol. 10: 1293 (1996), Enmark et al., Mol.Endocrinol. 10, 1293-1307 (1996) and Giguere, Endocrin. Rev. 20, 689-725(1999)). The conventional nuclear hormone receptors are generallytransactivators in the presence of ligand, and can either be activerepressors or transcriptionally inert in the absence of ligand. Some ofthe orphan receptors behave as if they are transcriptionally inert inthe absence of ligand. Others, however, behave as either constitutiveactivators or repressors. These orphan nuclear hormone receptors areeither under the control of ubiquitous ligands that have not beenidentified, or do not need to bind ligand to exert these activities.

In common with other transcription factors, the nuclear hormonereceptors have a modular structure, being comprised of three distinctdomains: an N-terminal domain of variable size containing atranscriptional activation function AF-1, a highly conserved DNA bindingdomain and a moderately conserved ligand-binding domain. Theligand-binding domain is not only responsible for binding the specificligand but also contains a transcriptional activation function calledAF-2 and a dimerisation domain (Wurtz et al., Nature Struc. Biol. 3,87-94 (1996), Parker et al., Nature Struc. Biol. 3, 113-115 (1996) andKumar et al., Steroids 64, 310-319 (1999)). Although the overall proteinsequence of these receptors can vary significantly, all share both acommon structural arrangement indicative of divergence from an ancestralarchetype, and substantial homology (especially, sequence identity) atthe ligand-binding domain.

The steroid binding nuclear hormone receptors (SB-NHR's) comprise asub-family of nuclear hormone receptors. These receptors are related inthat they share a stronger sequence homology to one another,particularly in the ligand binding domain (LBD), than to the othermembers of the NHR super-family (Evans, 1988, supra) and they allutilize steroid based ligands. Some examples of this sub-family of NHR'sare the androgen receptor (AR), the estrogen receptor (ER), theprogesterone receptor (PR), the glucocorticoid receptor (GR), themineralocorticoid receptor (MR), the aldosterone receptor (ALDR) and thesteroid and xenobiotic receptor (SXR) (Evans et al., WO 99/35246). Basedon the strong sequence homology in the LBD, several orphan receptors mayalso be members of the SB-NHR sub-family.

Consistent with the high sequence homology found in the LBD for each ofthe SB-NHR's, the natural ligands for each is derived from a commonsteroid core. Examples of some of the steroid based ligands utilized bymembers of the SB-NHR's include cortisol, aldosterone, estrogen,progesterone, testosterone and dihydrotestosterone. Specificity of aparticular steroid based ligand for one SB-NHR versus another isobtained by differential substitution about the steroid core. Highaffinity binding to a particular SB-NHR, coupled with high levelspecificity for that particular SB-NHR, can be achieved with only minorstructural changes about the steroid core (e.g., Waller et al., Toxicol.Appl. Pharmacol. 137, 219-227 (1996) and Mekenyan et al., Environ. Sci.Technol. 31, 3702-3711 (1997), binding affinity for progesterone towardsthe androgen receptor as compared to testosterone).

Numerous synthetically derived steroidal and non-steroidal agonists andantagonists have been described for the members of the SB-NHR family.Many of these agonist and antagonist ligands are used clinically in manto treat a variety of medical conditions. RU486 is an example of asynthetic agonist of the PR, which is utilized as a birth control agent(Vegeto et al., Cell 69: 703-713 (1992)), and Flutamide is an example ofan antagonist of the AR, which is utilized for the treatment of prostatecancer (Neri et al, Endo. 91, 427-437 (1972)). Tamoxifen is an exampleof a tissues specific modulator of the ER function, that is used in thetreatment of breast cancer (Smigel, J. Natl. Cancer Inst. 90, 647-648(1998)). Tamoxifen can function as an antagonist of the ER in breasttissue while acting as an agonist of the ER in bone (Grese et al., Proc.Natl. Acad. Sci. USA 94, 14105-14110 (1997)). Because of the tissueselective effects seen for Tamoxifen, this agent and agents like it arereferred to as “partial-agonist” or partial-antagonist”. In addition tosynthetically derived non-endogenous ligands, non-endogenous ligands forNHR's can be obtained from food sources (Regal et al., Proc. Soc. Exp.Biol. Med. 223, 372-378 (2000) and Hempstock et al., J. Med. Food 2,267-269 (1999)). The flavanoid phytoestrogens are an example of anunnatural ligand for SB-NHR's that are readily obtained from a foodsource such as soy (Quella et al., J. Clin. Oncol. 18, 1068-1074 (2000)and Banz et al., J. Med. Food 2, 271-273 (1999)). The ability tomodulate the transcriptional activity of individual NHR by the additionof a small molecule ligand, makes them ideal targets for the developmentof pharmaceutical agents for a variety of disease states.

As mentioned above, non-natural ligands can be synthetically engineeredto serve as modulators of the function of NHR's. In the case ofSB-NHR's, engineering of an unnatural ligand can include theidentification of a core structure which mimics the natural steroid coresystem. This can be achieved by random screening against severalSB-NHR's or through directed approaches using the available crystalstructures of a variety of NHR ligand binding domains (Bourguet et al.,Nature 375, 377-382 (1995), Brzozowski, et al., Nature 389, 753-758(1997), Shiau et al., Cell 95, 927-937 (1998) and Tanenbaum et al.,Proc. Natl. Acad. Sci. USA 95, 5998-6003 (1998)). Differentialsubstitution about such a steroid mimic core can provide agents withselectivity for one receptor versus another. In addition, suchmodifications can be employed to obtain agents with agonist orantagonist activity for a particular SB-NHR. Differential substitutionabout the steroid mimic core can result in the formation of a series ofhigh affinity agonists and antagonists with specificity for, forexample, ER versus PR versus AR versus GR versus MR. Such an approach ofdifferential substitution has been reported, for example, for quinolinebased modulators of steroid NHR in J. Med. Chem., 41, 623 (1999); WO9749709; U.S. Pat. No. 5,696,133; U.S. Pat. No. 5,696,130; U.S. Pat. No.5,696,127; U.S. Pat. No. 5,693,647; U.S. Pat. No. 5,693,646; U.S. Pat.No. 5,688,810; U.S. Pat. No. 5,688,808 and WO 9619458, all incorporatedherein by reference.

As illustrated in Scheme II, compounds of formula I can be obtained byreaction of a primary amine of formula V with a substitutedanhydride-like intermediate of formula VI, for example, in a solventsuch as acetic acid with or without heating, to yield a compound offormula IV, which is a compound of formula I. Primary amines of formulaV can be obtained from commercial sources or readily synthesized by oneskilled in the art. Anhydride-like agents of formula VI can be obtainedfrom commercial sources or readily synthesized by one skilled in theart. The documents listed following describe exemplary approaches forthe synthesis of intermediates of formula VI as well as syntheticapproaches which can be applied to the synthesis of compounds of formulaIV (all incorporated herein by reference in their entirety): Kohler, E.P.; Tishler, M.; Potter, H.; Thompson, H.

The aforementioned approach(es) can be applied in a combinatorialfashion, for example, by utilizing a multi-well reaction block such asis described in Waldemar Ruediger, Wen-Jeng Li, John W., Allen Jr., andHarold N. Weller III, U.S. Pat. No. 5,961,925, Apparatus for Synthesisof Multiple Organic Compounds With Pinch Valve Block (incorporatedherein by reference in its entirety). By utilizing the above-mentionedmulti-well reaction block, one can, for example, perform multiples of 96reactions at a time. Solvent can then be removed from the reaction tubeswithout removal from the reaction block and the crude products can beprecipitated using a base such as sodium bicarbonate. The precipitatescan be collected by filtration of the reaction block and then thedesired products can be transferred directly to 96 well plates forscreening. In this fashion, a large array of compounds of formula I canbe synthesized, and tests conducted as desired by an automated approach.

Scheme III describes a method for preparing an intermediate compound offormula VI which can be used to synthesize a compound of formula I, asdescribed in Scheme II. As described in Scheme III, a diene of formulaII can be reacted with a dieneophile of formula VII to yield theintermediate of formula VI. The methods applied to obtain such atransformation are analogous to those described in Scheme I.

Scheme IV describes a method for preparing an intermediate compound offormula VI which can be used to synthesize a compound of formula I, asdescribed in Scheme II. As shown in Scheme IV, a diene of formula II canbe reacted with a dieneophile of formula VIII to yield the intermediateof formula IX. The intermediate of formula IX can be dehydrated to ananhydride-like intermediate of formula VI. Dehydration of the bis-acidintermediate of formula IX to can be achieved by a variety of methods,such as those known to one skilled in the art and described in thefollowing documents and the references embodied therein: Sprague et al.,J. Med. Chem. 28, 1580-1590 (1985); and/or Retemi et al., J. Org. Chem.61, 6296-6301 (1996).

Schemes I to IV describe general methods for the synthesis of compoundsof formula I, and intermediates thereof, in which substitution about thering system is incorporated directly, for example, at the level of theintermediate diene, dienophile, anhydride-like intermediate and aminegroups. In addition to these approaches, additional substitution can beincorporated onto an already-prepared compound of formula I by a varietyof approaches to prepare other compounds of the formula I. Exemplarymethods for further substitution are described in Schemes V to XI.

Scheme V describes one such approach to incorporating additionalsubstitution into a structure of formula I. As illustrated in Scheme V,a compound of formula X, which is a compound of formula I where A₁ andA₂ are CR⁷, W is NH—CHR⁷ and Y is CHR⁷—CHR⁷, can be functionalized atthe free amine of the group W by reaction with any of a variety ofelectrophilic agents such as acid halides or alkyl halides in thepresence of base, for example, by methods known by one skilled in theart. In Scheme V, X is a leaving group, and a compound of formula XI isa compound of formula I where A₁ and A₂ are CR⁷, W is NR⁷—CHR⁷ and Y isCHR⁷—CHR⁷.

Scheme VI describes an additional approach for further incorporatingsubstitution onto a compound of formula I. As illustrated in Scheme VI,a compound of formula XII, which is a compound of formula I where A₁ andA₂ are CR⁷, W is S—CHR⁷ and Y is CHR⁷—CHR⁷, can be partially oxidizedwith an oxidizing agent such as mCPBA or other agents such as thoseknown to one skilled in the art, to give the sulfoxide analog of formulaXIII, which is a compound of formula I where A₁ and A₂ are CR⁷, W isSO—CHR and Y is CHR⁷—CHR⁷. Further treatment of a compound of formulaXIII with an oxidizing agent such as mCPBA or other agents such as thoseknown to one skilled in the art, can yield the sulphone analog offormula XIV, which is a compound of formula I where A₁ and A₂ are CR⁷, Wis SO₂—CHR⁷ and Y is CHR⁷—CHR⁷. Alternatively, a compound of formula XIIcan be converted directly to a compound of formula XIV by prolongedtreatment with an oxidizing agent, such as mCPBA, or with other agentssuch as those known to one skilled in the art.

Scheme VII describes another approach to incorporating additionalsubstitution onto a compound of formula I. As illustrated in Scheme VII,a diene of formula IIa can be reacted with a dienophile of formula III,as described in Scheme I, to yield a compound of formula IVa, which is acompound of formula I where Y is O, A₂ is CR⁷ and A₁ is C—(CH₂)_(q)-T.The compound of formula IVa can be reacted with a reagent of formulaR¹²-T′ to obtain a compound of formula IVb or IVc which are compounds offormula I where Y is O, A₂ is CR⁷ and A₁ is C—(CH₂)_(q)-T′-R¹² orC—(CH₂)_(q)-T-R¹², respectively. The reagent R¹²-T′ can be obtained fromcommercial sources or can readily be prepared by one skilled in the art.

In the above Scheme, R¹² has the same definition as R⁷ defined earlier,q is zero or an integer from 0-8, and T is defined either as (1) anucleophilic center such as, but not limited, to a nitrogen, oxygen orsulfur-containing group, capable of undergoing a nucleophilicsubstitution reaction with the leaving group T′ or (2) a leaving groupcapable undergoing a nucleophilic substitution reaction with anucleophilic group T′ (such as, but not limited, to a nitrogen, oxygenor sulfur-containing nucleophilic group). T′ has the same definition asT. In the present case, for example, a nucleophilic substitutionreaction occurs when the attacking reagent (the nucleophile) brings anelectron pair to the substrate, using this pair to form the new bond,and the leaving group (the nucleofuge) comes away with the electronpair, leaving as an anionic intermediate. For a detailed discussion ofthe mechanism of aliphatic nucleophilic substitutions and a review ofspecific aliphatic nucleophilic substitution reactions see AdvancedOrganic Chemistry, Reactions, Mechanisms, and Structure, 4^(th)Addition. Jerry March (Ed.), John Wiley & Sons, New York (1992) 293-500and the references therein. Compounds of the formulae IVa, IVb, or IVcmay, of course, be employed in the methods described herein (especially,in the treatment of nuclear hormone receptor-associated conditions)without undergoing further reaction of T or T′.

An alternate approach to compounds of formula IVa, IVb and IVc isillustrated in Scheme VIII. For this approach, techniques such as thosedescribed in Schemes II, III and IV can be applied to the preparation ofan intermediate of formula VIa, where T and q are as defined in SchemeVII. The intermediate of formula VIa can be reacted with a substititedamine of formula V, as described in Scheme II, to yield the compound offormula IVa, which is a compound of formula I where Y is O, A₂ is CR⁷and A₁ is C—(CH₂)_(q)-T. The compound of formula IVa can be treated inthe manner described in Scheme VII to obtain compounds of formula IVb orIVc which are compounds of formula I where Y is O, A₂ is CR⁷ and A₁ isC—(CH₂)_(q)-T′-R¹² or C—(CH₂)_(q)-T-R¹², respectively.

Scheme IX describes another approach to incorporating furthersubstitution onto a compound of formula I. As illustrated in Scheme IX(where X is a leaving group), a diene of formula IIb can be reacted witha dienophile of formula III, as described in Scheme I, to yield acompound of formula IVe, which is a compound of formula I where Y is NH,and A₁ and A₂ are CR⁷. The compound of formula IVe can be functionalizedat the free amine by reacting with a variety of electrophilic agentssuch as acid halides or alkyl halides in the presence of base, forexample by methods known by one skilled in the art and described inScheme V, to yield a compound of formula IVf, which is a compound offormula I where Y is NR⁷ and A₁ and A₂ are CR⁷.

An alternate approach to compounds of formula IVe and IVf is illustratedin Scheme X. For this approach, techniques as described in Schemes II,III and IV can be applied to the preparation of an intermediate offormula VIb. The intermediate of formula VIb can be reacted with asubstituted amine of formula V, as described in Scheme II, to yield acompound of formula IVe, which is a compound of formula I where Y is NH,and A₁ and A₂ are CR⁷. The latter intermediate can be treated in themanner described in Scheme V to obtain a compound of formula IVf, whichis a compound of formula I where Y is NR⁷, and A₁ and A₂ are CR⁷.

Scheme XI describes another approach to incorporating additionalsubstitution onto a compound of formula I. As illustrated in Scheme XI,a diene of formula IIc can be reacted with a dienophile of formula III,as described in Scheme I, to yield a compound of formula IVg, which is acompound of formula I where Y is SO and A₁ and A₂ are CR⁷. A compound offormula IVg can be treated with an oxidizing agent such as mCPBA, asdescribed in Scheme VI, to yield a compound of formula IVh, which is acompound of formula I where Y is SO₂ and A₁ and A₂ are CR⁷.

Scheme XII describes another approach to incorporating additionalsubstitution onto a compound of formula I. As illustrated in Scheme XII,a compound of formula XV, which can be prepared in accordance with theabove Schemes, can be incubated in the presence of a suitable enzyme ormicroorganism resulting in the formation of a hydroxylated analog offormula XVI. Such a process can be employed to yield regiospecific aswell as enantiospecific incorporation of a hydroxyl group into amolecule of formula XV by a specific microorganism or by a series ofdifferent microorganisms. Such microorganisms can, for example, bebacterial, yeast or fungal in nature and can be obtained fromdistributors such as ATCC or identified for use in this method such asby methods known to one skilled in the art. Compound XVI is a compoundof formula I where Y is as described above and A¹ and A₂ are preferablyCR⁷.

Scheme XIII describes another approach to incorporating additionalsubstitution onto a compound of formula I. As illustrated in SchemeXIII, a compound of formula XVII, which can be prepared in accordancewith the above Schemes, can be incubated in the presence of a suitableenzyme or microorganism resulting in the formation of a diol analog offormula XVIII. Such a process can be employed to yield regiospecific aswell as enantiospecific transformation of a compound of formula XVII toa 1-2 diol of formula XVIII by a specific microorganism or by a seriesof different microorganisms. Such microorganisms can, for example, bebacterial, yeast or fungal in nature and can be obtained fromdistributors such as ATCC or identified for use in this method such asby methods known to one skilled in the art. Compound XVIII is a compoundof formula I where Y is as described above and A₁ and A₂ are preferablyCR⁷.

The present invention also provides the methods of Schemes XII and XIII.

Thus, in one embodiment, the present invention provides a method forpreparation of a compound of the following formula XVI, or salt thereof:

where the symbols are as defined herein,

-   -   comprising the steps of contacting a compound of the following        formula XV, or salt thereof:        where the symbols are as defined above;    -   with an enzyme or microorganism capable of catalyzing the        hydroxylation of said compound XV to form said compound XVI, and        effecting said hydroxylation.

In another preferred embodiment, the present invention provides a methodfor preparation of a compound of the following formula XVIII, or saltthereof:

where the symbols are as defined herein,

-   -   comprising the steps of contacting a compound of the following        formula XVII, or salt thereof:        where the symbols are as defined above;    -   with an enzyme or microorganism capable of catalyzing the        opening of the epoxide ring of compound XVII to form the diol of        said compound XVIII, and effecting said ring opening and diol        formation.

All stereoconfigurations of the unspecified chiral centers of thecompounds of the formulae XV, XVI, XVII and XVIII are contemplated inthe methods of the present invention, either alone (that is,substantially free of other stereoisomers) or in admixture with otherstereoisomeric forms. Conversion of one isomer selectively (e.g.,hydroxylation of the exo isomer preferentially to hydroxylation of theendo isomer) when contacting an isomeric mixture is a preferredembodiment of the invention. Conversion to one isomer selectively (e.g.,hydroxylation on the exo face “exo isomer” preferentially to the endoface “endo isomer” or regioselective opening of an epoxide to form onlyone of two possible regioisomers of a trans diol) is a preferredembodiment of the invention. Hydroxylation of an achiral intermediate toform a single optical isomer of the hydroxylated product is also apreferred embodiment of the invention. Resolution of a recemic mixtureof an intermediate by selective hydroxylation, or epoxide ring openingand diol formation, to generate one of the two possible optical isomersis also a preferred embodiment of the invention. The term “resolution”as used herein denotes partial, as well as, preferably, completeresolution.

The terms “enzymatic process” or “enzymatic method”, as used herein,denote a process or method of the present invention employing an enzymeor microorganism. The term “hydroxylation”, as used herein, denotes theaddition of a hydroxyl group to a methylene group as described above.Hydroxylation can be achieved, for example, by contact with molecularoxygen according to the methods of the present invention. Diol formationcan be achieved, for example, by contact with water according to themethods of the present invention. Use of “an enzyme or microorganism” inthe present methods includes use of two or more, as well as a single,enzyme or microorganism.

The enzyme or microorganism employed in the present invention can be anyenzyme or microorganism capable of catalyzing the enzymatic conversionsdescribed herein. The enyzmatic or microbial materials, regardless oforigin or purity, can be employed in the free state or immobilized on asupport such as by physical adsorption or entrapment. Microorganisms orenzymes suitable for use in the present invention can be selected byscreening for the desired activity, for example, by contacting acandidate microorganism or enzyme with a starting compound XV or XVII orsalt thereof, and noting conversion to the corresponding compound XVI orXVIII or salt thereof. The enzyme may, for example, be in the form ofanimal or plant enzymes or mixtures thereof, cells of microorganisms,crushed cells, extracts of cells, or of synthetic origin.

Exemplary microorganisms include those within the genera: Streptomycesor Amycolatopsis. Particularly preferred microorganisms are those withinthe species Streptomyces griseus, especially Streptomyces griseus ATCC10137, and Amycolatopsis orientalis such as ATCC 14930, ATCC 21425, ATCC35165, ATCC 39444, ATCC 43333, ATCC 43490, ATCC 53550, ATCC 53630, andespecially ATCC 43491. The term “ATCC” as used herein refers to theaccession number of the American Type Culture Collection, 10801University Blvd., Manassas Va. 20110-2209, the depository for theorganism referred to. It should be understood that mutants of theseorganisms are also contemplated by the present invention, for use in themethods described herein, such as those modified by the use of chemical,physical (for example, X-rays) or biological means (for example, bymolecular biology techniques).

Preferred enzymes include those derived from microorganisms,particularly those microorganisms described above. Enzymes may beisolated, for example, by extraction and purification methods such as bymethods known to those of ordinary skill in the art. An enzyme may, forexample, be used in its free state or in immobilized form. Oneembodiment of the invention is that where an enzyme is adsorbed onto asuitable carrier, e.g., diatomaceous earth (porous Celite HyfloSupercel), microporous polypropylene (Enka Accurel® polypropylenepowder), or a nonionic polymeric adsorbent such as Amberlite® XAD-2(polystyrene) or XAD-7 (polyacrylate) from Rohm and Haas Co. Whenemployed to immobilize an enzyme, a carrier may control the enzymeparticle size and prevent aggregation of the enzyme particles when usedin an organic solvent. Immobilization can be accomplished, for example,by precipitating an aqueous solution of the enzyme with cold acetone inthe presence of the Celite Hyflo Supercel followed by vacuum drying, orin the case of a nonionic polymeric adsorbent, incubating enzymesolutions with adsorbent on a shaker, removing excess solution anddrying enzyme-adsorbent resins under vacuum. While it is desirable touse the least amount of enzyme possible, the amount of enzyme requiredwill vary depending upon the specific activity of the enzyme used.

Hydroxylation as described above can occur in vivo. For example, liverenzyme can selectively, relative to the endo isomer, hydroxylate the exoisomer of a compound of the present invention. In conducting the methodsof the present invention outside the body, liver microsomal hydroxylasecan be employed as the enzyme for catalysis.

These processes may also be carried out using microbial cells containingan enzyme having the ability to catalyze the conversions. When using amicroorganism to perform the conversion, these procedures areconveniently carried out by adding the cells and the starting materialto the desired reaction medium.

Where microorganisms are employed, the cells may be used in the form ofintact wet cells or dried cells such as lyophilized, spray-dried orheat-dried cells, or in the form of treated cell material such asruptured cells or cell extracts. Cell extracts immobilized on Celite® orAccurel® polypropylene as described earlier may also be employed. Theuse of genetically engineered organisms is also contemplated. The hostcell may be any cell, e.g. Escherichia coli, modified to contain a geneor genes for expressing one or more enzymes capable of catalysis asdescribed herein.

Where one or more microorganisms are employed, the enzymatic methods ofthe present invention may be carried out subsequent to the fermentationof the microorganism (two-stage fermentation and conversion), orconcurrently therewith, that is, in the latter case, by in situfermentation and conversion (single-stage fermentation and conversion).

Growth of the microorganisms can be achieved by one of ordinary skill inthe art by the use of an appropriate medium. Appropriate media forgrowing microorganisms include those which provide nutrients necessaryfor the growth of the microbial cells. A typical medium for growthincludes necessary carbon sources, nitrogen sources, and elements (e.g.in trace amounts). Inducers may also be added. The term “inducer”, asused herein, includes any compound enhancing formation of the desiredenzymatic activity within the microbial cell.

Carbon sources can include sugars such as maltose, lactose, glucose,fructose, glycerol, sorbitol, sucrose, starch, mannitol, propyleneglycol, and the like; organic acids such as sodium acetate, sodiumcitrate, and the like; and alcohols such as ethanol, propanol and thelike.

Nitrogen sources can include N-Z amine A, corn steep liquor, soy beanmeal, beef extracts, yeast extracts, molasses, baker's yeast, tryptone,nutrisoy, peptone, yeastamin, amino acids such as sodium glutamate andthe like, sodium nitrate, ammonium sulfate and the like.

Trace elements can include magnesium, manganese, calcium, cobalt,nickel, iron, sodium and potassium salts. Phosphates may also be addedin trace or, preferably, greater than trace amounts.

The medium employed can include more than one carbon or nitrogen sourceor other nutrient.

Preferred media for growth include aqueous media.

The agitation and aeration of the reaction mixture affects the amount ofoxygen available during the conversion process when conducted, forexample, in shake-flask cultures or fermentor tanks during growth ofmicroorganisms.

Incubation of the reaction medium is preferably at a temperature betweenabout 4 and about 60° C. The reaction time can be appropriately varieddepending upon the amount of enzyme used and its specific activity.Reaction times may be reduced by increasing the reaction temperatureand/or increasing the amount of enzyme added to the reaction solution.

It is also preferred to employ an aqueous liquid as the reaction medium,although an organic liquid, or a miscible or immiscible (biphasic)organic/aqueous liquid mixture, may also be employed. The amount ofenzyme or microorganism employed relative to the starting material isselected to allow catalysis of the enzymatic conversions of the presentinvention.

Solvents for the organic phase of a biphasic solvent system may be anyorganic solvent immiscible in water, such as toluene, cyclohexane,xylene, trichlorotrifluoroethane and the like. The aqueous phase isconveniently of water, preferably deionized water, or a suitable aqueousbuffer solution, especially a phosphate buffer solution. The biphasicsolvent system preferably comprises between about 10 to 90 percent byvolume of organic phase and between about 90 to 10 percent by volume ofaqueous phase, and most preferably contains at or about 20 percent byvolume of organic phase and at or about 80 percent by volume of theaqueous phase.

An exemplary embodiment of such processes starts with preparation of anaqueous solution of the enzyme(s) or microbes to be used. For example,the preferred enzyme(s) or microbes can be added to a suitable amount ofan aqueous solvent, such as phosphate buffer or the like. This mixtureis preferably adjusted to and maintained at a desired pH.

The compounds XVI and XVIII produced by the processes of the presentinvention can be isolated and purified, for example, by methods such asextraction, distillation, crystallization, and column chromatography.

Preferred are those compounds with anactivity greater than 20 μm for binding or transactivation in any ofthese assays. Various compounds of the present invention were determinedto have AR modulator activity utilizing the transactivation assay, andstandard AR binding assays as described following.

Transactivation Assays:

AR Specific Assay:

Compounds of the present invention were tested in transactivation assaysof a transfected reporter construct and using the endogenous androgenreceptor of the host cells. The transactivation assay provides a methodfor identifying functional agonists and partial agonists that mimic, orantagonists that inhibit, the effect of native hormones, in this case,dihydrotestosterone (DHT). This assay can be used to predict in vivoactivity as there is a good correlation in both series of data. See,e.g. T. Berger et al., J. Steroid Biochem. Molec. Biol. 773 (1992), thedisclosure of which is herein incorporated by reference.

For the transactivation assay a reporter plasmid is introduced bytransfection (a procedure to induce cells to take foreign genes) intothe respective cells. This reporter plasmid, comprising the cDNA for areporter protein, such as secreted alkaline phosphatase (SEAP),controlled by prostate specific antigen (PSA) upstream sequencescontaining androgen response elements (AREs). This reporter plasmidfunctions as a reporter for the transcription-modulating activity of theAR. Thus, the reporter acts as a surrogate for the products (mRNA thenprotein) normally expressed by a gene under control of the AR and itsnative hormone. In order to detect antagonists, the transactivationassay is carried out in the presence of constant concentration of thenatural AR hormone (DHT) known to induce a defined reporter signal.Increasing concentrations of a suspected antagonist will decrease thereporter signal (e.g., SEAP production). On the other hand, exposing thetransfected cells to increasing concentrations of a suspected agonistwill increase the production of the reporter signal.

For this assay, LNCaP and MDA 453 cells were obtained from the AmericanType Culture Collection (Rockville, Md.), and maintained in RPMI 1640 orDMEM medium supplemented with 10% fetal bovine serum (FBS; Gibco)respectively. The respective cells were transiently transfected byelectroporation according to the optimized procedure described byHeiser, 130 Methods Mol. Biol., 117 (2000), with thepSEAP2/PSA540/Enhancer reporter plasmid. The reporter plasmid, wasconstructed as follows: commercial human placental genomic DNA was usedto generate by Polymerase Cycle Reaction (PCR) a fragment containing theBglII site (position 5284) and the Hind III site at position 5831 of thehuman prostate specific antigen promoter (Accession # U37672), Schuur,et al., J. Biol. Chem., 271 (12): 7043-51 (1996). This fragment wassubcloned into the pSEAP2/basic (Clontech) previously digested withBglII and HindIII to generate the pSEAP2/PSA540 construct. Then afragment bearing the fragment of human PSA upstream sequence betweenpositions −5322 and −3873 was amplified by PCR from human placentalgenomic DNA. A XhoI and a BglII sites were introduced with the primers.The resulting fragment was subcloned into pSEAP2/PSA540 digested withXhoI and BglII respectively, to generate the pSEAP2/PSA540/Enhancerconstruct. LNCaP and MDA 453 cells were collected in media containing10% charcoal stripped FBS. Each cell suspension was distributed into twoGene Pulser Cuvetts (Bio-Rad) which then received 8 μg of the reporterconstruct, and electoporated using a Bio-Rad Gene Pulser at 210 voltsand 960 μFaraday. Following the transfections the cells were washed andincubated with media containing charcoal stripped fetal bovine serum inthe absence (blank) or presence (control) of 1 nM dihydrotestosterone(DHT; Sigma Chemical) and in the presence or absence of the standardanti-androgen bicalutamide or compounds of the present invention inconcentrations ranging from 10-10 to 10-5 M (sample). Duplicates wereused for each sample. The compound dilutions were performed on a Biomek2000 laboratory workstation. After 48 hours, a fraction of thesupernatant was assayed for SEAP activity using the Phospha-LightChemiluminescent Reporter Gene Assay System (Tropix, Inc). Viability ofthe remaining cells was determined using the CellTiter 96 AqueousNon-Radioactive Cell Proliferation Assay (MTS Assay, Promega). Briefly,a mix of a tetrazolium compound(3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium,inner salt; MTS) and an electron coupling reagent (phenazinemethosulfate; PMS) are added to the cells. MTS (Owen's reagent) isbioreduced by cells into a formazan that is soluble in tissue culturemedium, and therefore its absorbance at 490 nm can be measured directlyfrom 96 well assay plates without additional processing. The quantity offormazan product as measured by the amount of 490 nm absorbance isdirectly proportional to the number of living cells in culture. For eachreplicate the SEAP reading was normalized by the Abs490 value derivedfrom the MTS assay. For the antagonist mode, the % Inhibition wascalculated as:% Inhibition=100×(1−[average control−average blank/averagesample−average blank])

Data was plotted and the concentration of compound that inhibited 50% ofthe normalized SEAP was quantified (IC₅₀).

For the agonist mode % Control was referred as the effect of the testedcompound compared to the maximal effect observed with the naturalhormone, in this case DHT, and was calculated as:% Control=100×average sample−average blank/average control−average blank

Data was plotted and the concentration of compound that activates tolevels 50% of the normalized SEAP for the control was quantified (EC₅₀).

GR Specificity Assay:

The reporter plasmid utilized was comprised of the cDNA for the reporterSEAP protein, as described for the AR specific transactivation assay.Expression of the reporter SEAP protein was controlled by the mousemammary tumor virus long terminal repeat (MMTV LTR) sequences thatcontains three hormone response elements (HREs) that can be regulated byboth GR and PR see, e.g. G. Chalepakis et al., Cell, 53(3), 371 (1988).This plasmid was transfected into A549 cells, which expresses endogenousGR, to obtain a GR specific transactivation assay. A549 cells wereobtained from the American Type Culture Collection (Rockville, Md.), andmaintained in RPMI 1640 supplemented with 10% fetal bovine serum (FBS;Gibco). Determination of the GR specific antagonist activity of thecompounds of the present invention was identical to that described forthe AR specific transactivation assay, except that the DHT was replacedwith 5 nM dexamethasone (Sigma Chemicals), a specific agonist for GR.Determination of the GR specific agonist activity of the compounds ofthe present invention was performed as described for the ARtransactivation assay, wherein one measures the activation of the GRspecific reporter system by the addition of a test compound, in theabsence of a known GR specific agonists ligand.

PR Specific Assay:

The reporter plasmid utilized was comprised of the cDNA for the reporterSEAP protein, as described for the AR specific transactivation assay.Expression of the reporter SEAP protein was controlled by the mousemammary tumor virus long terminal repeat (MMTV LTR) sequences thatcontains three hormone response elements (HREs) that can be regulated byboth GR and PR. This plasmid was transfected into T47D, which expressesendogenous PR, to obtain a PR specific transactivation assay. T47D cellswere obtained from the American Type Culture Collection (Rockville,Md.), and maintained in DMEM medium supplemented with 10% fetal bovineserum (FBS; Gibco). Determination of the PR specific antagonist activityof the compounds of the present invention was identical to thatdescribed for the AR specific transactivation assay, except that the DHTwas replaced with 1 nM Promegastone (NEN), a specific agonist for PR.Determination of the PR specific agonist activity of the compounds ofthe present invention was performed as described for the ARtransactivation assay, wherein one measures the activation of the PRspecific reporter system by the addition of a test compound, in theabsence of a known PR specific agonists ligand.

AR Binding Assay:

For the whole cell binding assay, human LNCaP cells (T877A mutant AR) orMDA 453 (wild type AR) in 96-well microtiter plates containing RPMI 1640or DMEM supplemented with 10% charcoal stripped CA-FBS (CocalecoBiologicals) respectively, were incubated at 37° C. to remove anyendogenous ligand that might be complexed with the receptor in thecells. After 48 hours, either a saturation analysis to determine theK_(d) for tritiated dihydrotestosterone, [³H]-DHT, or a competitivebinding assay to evaluate the ability of test compounds to compete with[³H]-DHT were performed. For the saturation analysis, media (RPMI 1640or DMEM-0.2% CA-FBS) containing [³H]-DHT (in concentrations ranging from0.1 nM to 16 nM) in the absence (total binding) or presence(non-specific binding) of a 500-fold molar excess of unlabeled DHT wereadded to the cells. After 4 hours at 37° C., an aliquot of the totalbinding media at each concentration of [³H]-DHT was removed to estimatethe amount of free [³H]-DHT. The remaining media was removed, cells werewashed three times with PBS and harvested onto UniFilter GF/B plates(Packard), Microscint (Packard) was added and plates counted in aTop-Counter (Packard) to evaluate the amount of bound [³H]-DHT.

For the saturation analysis, the difference between the total bindingand the non-specific binding, was defined as specific binding. Thespecific binding was evaluated by Scatchard analysis to determine theK_(d) for [³H]-DHT. See e.g. D. Rodbard, Mathematics and statistics ofligand assays: an illustrated guide: In: J. Langon and J. J. Clapp,eds., Ligand Assay, Masson Publishing U.S.A., Inc., New York, pp. 45-99,(1981), the disclosure of which is herein incorporated by reference.

For the competition studies, media containing 1 nM [³H]-DHT andcompounds of the invention (“test compounds”) in concentrations rangingfrom 10⁻¹⁰ to 10⁻⁵ M were added to the cells. Two replicates were usedfor each sample. After 4 hours at 37° C., cells were washed, harvestedand counted as described above. The data was plotted as the amount of[³H]-DHT (% of control in the absence of test compound) remaining overthe range of the dose response curve for a given compound. Theconcentration of test compound that inhibited 50% of the amount of[³H]-DHT bound in the absence of competing ligand was quantified (IC₅₀)after log-logit transformation. The K₁ values were determined byapplication of the Cheng-Prusoff equation to the IC₅₀ values, where:$K_{I} = {\frac{{IC}_{50}}{\left( {1 + {{\left( {{\,^{3}H}\text{-}{DHT}} \right)/K_{d}}\quad{for}\quad{\,^{3}H}\text{-}{DHT}}} \right)}.}$

After correcting for non-specific binding, IC₅₀ values were determined.The IC₅₀ is defined as the concentration of competing ligand needed toreduce specific binding by 50%. The K_(d)s for [³H]-DHT for MDA 453 andLNCaP were 0.7 and 0.2 nM respectively.

Human Prostate Cell Proliferation Assay:

Compounds of the present invention were tested (“test compounds”) on theproliferation of human prostate cancer cell lines. For that, MDA PCa2bcells, a cell line derived from the metastasis of a patient that failedcastration, Navone et al., Clin. Cancer Res., 3, 2493-500 (1997), wereincubated with or without the test compounds for 72 hours and the amountof [³H]-thymidine incorporated into DNA was quantified as a way toassess number of cells and therefore proliferation. The MDA PCa2b cellline was maintained in BRFF-HPC1 media (Biological Research Faculty &Facility Inc., Md.) supplemented with 10% FBS. For the assay, cells wereplated in Biocoated 96-well microplates and incubated at 37° C. in 10%FBS (charcoal-stripped)/BRFF-BMZERO (without androgens). After 24 hours,the cells were treated in the absence (blank) or presence of 1 nM DHT(control) or with test compounds (sample) of the present invention inconcentrations ranging from 10⁻¹⁰ to 10⁻⁵ M. Duplicates were used foreach sample. The compound dilutions were performed on a Biomek 2000laboratory work station. Seventy two hours later 0.44 uCi. of[³H]-Thymidine (Amersham) was added per well and incubated for another24 h followed by tripsinization, harvesting of the cells onto GF/Bfilters. Micro-scint PS were added to the filters before counting themon a Beckman TopCount.

The % Inhibition was calculated as:%Inhibition=100×(1−[average_(control)−average_(blank)/average_(sample)−average_(blank)])Data was plotted and the concentration of compound that inhibited 50% ofthe [³H]-Thymidine incorporation was quantified (IC₅₀).C2C12 Mouse Myoblast Transactivation Assay:

Two functional transactivation assays were developed to assess theefficacy of androgen agonists in a muscle cell background using aluciferase reporter. The first assay (ARTA Stable 1) uses a cell line,Stable 1 (clone #72), which stably expresses the full length ratandrogen receptor but requires the transient transfection of anenhancer/reporter. This cell line was derived from C2C12 mouse moyoblastcells. The second assay (ARTA Stable 2) uses a cell line, Stable 2(clone #133), derived from Stable 1 which stably expresses both rAR andthe enhancer/luciferase reporter.

The enhancer/reporter construct used in this system ispGL3/2XDR-1/luciferase. 2XDR-1 was reported to be an AR specificresponse element in CV-1 cells, Brown et. al. The Journal of BiologicalChemisty 272, 8227-8235, (1997). It was developed by random mutagenesisof an AR/GR consensus enhancer sequence.

No. 09/885,831, entitled “Cell        Lines and Cell-BasedAssays for Identification of Androgen        Receptor Modulators” filed Jun. 20, 2001 by Jacek Ostrowski et        al. (Attorney Docket No. D0177), which patent application is        incorporated herein by reference in its entirety.        Proliferation Assays        Murine Breast Cell Proliferation Assay:

The ability of compounds of the present invention (“test compounds”) tomodulate the function of the AR was determined by testing said compoundsin a proliferation assay using the androgen responsive murine breastcell line derived from the Shionogi tumor, Hiraoka et al., Cancer Res.,47, 6560-6564 (1987). Stable AR dependent clones of the parentalShionogi line were established by passing tumor fragments under thegeneral procedures originally described in Tetuo, et. al., CancerResearch 25, 1168-1175 (1965). From the above procedure, one stableline, SC114, was isolated, characterized and utilized for the testing ofexample compounds. SC114 cells were incubated with or without the testcompounds for 72 hours and the amount of [3H]-thymidine incorporatedinto DNA was quantified as a surrogate endpoint to assess the number ofcells and therefore the proliferation rate as described in Suzuki et.al., J. Steroid Biochem. Mol. Biol. 37, 559-567 (1990). The SC114 cellline was maintained in MEM containing 10⁻⁸ M testosterone and 2%DCC-treated FCS. For the assay, cells were plated in 96-well microplatesin the maintenance media and incubated at 37° C. On the following day,the medium was changed to serum free medium [Ham's F-12:MEM (1;1, v/v)containing 0.1% BSA] with (antagonist mode) or without (agonist mode)10⁻⁸ M testosterone and the test compounds of the present invention inconcentrations ranging from 10⁻¹⁰ to 10⁻⁵ M. Duplicates were used foreach sample. The compound dilutions were performed on a Biomek 2000laboratory work station. Seventy two hours later 0.44 uCi of[3H]-Thymidine (Amersham) was added per well and incubated for another 2hr followed by tripsinization, and harvesting of the cells onto GF/Bfilters. Micro-scint PS were added to the filters before counting themon a Beckman TopCount.

For the antagonist mode, the % Inhibition was calculated as:%Inhibition=100×(1−[average_(sample)−average_(blank)/average_(control)−average_(blank)])Data was plotted and the concentration of compound that inhibited 50% ofthe [³H]-Thymidine incorporation was quantified (IC₅₀).

For the agonist mode % Control was referred as the effect of the testedcompound compared to the maximal effect observed with the naturalhormone, in this case DHT, and was calculated as:%Control=100×(average_(sample)−average_(blank))/(average_(control)−average_(blank))Data was plotted and the concentration of compound that inhibited 50% ofthe [³H]-Thymidine incorporation was quantified (EC₅₀).In Vitro Assay to Measure GR Induced AP-1 Transrepression:

The AP-1 assay is a cell based luciferase reporter assay. A549 cells,which contain endogenous glucocorticoid receptor, were stablytransfected with an AP-1 DNA binding site attached to the luciferasegene. Cells are then grown in RPMI+10% fetal calf serum(charcoal-treated)+Penicillin/Streptomycin with 0.5 mg/ml geneticin.Cells are plated the day before the assay at approximately 40000cells/well. On assay day, the media is removed by aspiration and 20 μlassay buffer (RPMI without phenol red+10% FCS(charcoal-treated)+Pen/Strep) is added to each well. At this pointeither 20 μl assay buffer (control experiments), the compounds of thepresent invention (“test compounds”) (dissolved in DMSO and added atvarying concentrations) or dexamethasome (100 nM in DMSO, positivecontrol) are added to each well. The plates are then pre-incubated for15 minutes at 37° C., followed by stimulation of the cells with 10 ng/mlPMA. The plates are then incubated for 7 hrs at 37° C. after which 40 μlluciferase substrate reagent is added to each well. Activity is measuredby analysis in a luminometer as compared to control experiments treatedwith buffer or dexamethasome. Activity is designated as % inhibition ofthe reporter system as compared to the buffer control with 10 ng/ml PMAalone. The control, dexamethasone, at a concentration of ≦10 μMtypically suppresses activity by 65%. Test compounds which demonstratean inhibition of PMA induction of 50% or greater at a concentration oftest compound of <10 μM are deemed active.

Wet Prostate Weight Assay AR Antagonist Assay:

The activity of compounds of the present invention as AR antagonists wasinvestigated in an immature male rat model, a standard, recognized testof antiandrogen activity of a given compound, as described in L. G.Hershberger et al., Proc. Soc. Expt. Biol. Med., 83, 175 (1953); P. C.Walsh and R. F. Gittes, “Inhibition of extratesticular stimuli toprostate growth in the castrated rat by antiandrogens”, Endocrinology,86, 624 (1970); and B. J. Furr et al., “ICI 176,334: A novelnon-steroid, peripherally selective antiandrogen”, J. Endocrinol., 113,R7-9 (1987), the disclosures of which are herein incorporated byreference.

The basis of this assay is the fact that male sexual accessory organs,such as the prostate and seminal vesicles, play an important role inreproductive function. These glands are stimulated to grow and aremaintained in size and secretory function by the continued presence ofserum testosterone (T), which is the major serum androgen (>95%)produced by the Leydig cells in the testis under the control of thepituitary luteinizing hormone (LH) and follicle stimulating hormone(FSH). Testosterone is converted to the more active form,dihydrotestosterone, (DHT), within the prostate by 5α-reductase. Adrenalandrogens also contribute about 20% of total DHT in the rat prostate,compared to 40% of that in 65-year-old men. F. Labrie et al. Clin.Invest. Med., 16, 475-492 (1993). However, this is not a major pathway,since in both animals and humans, castration leads to almost completeinvolution of the prostate and seminal vesicles without concomitantadrenalectomy. Therefore, under normal conditions, the adrenals do notsupport significant growth of prostate tissues. M. C. Luke and D. S.Coffey, “The Physiology of Reproduction” ed. By E. Knobil and J. D.Neill, 1, 1435-1487 (1994). Since the male sex organs are the tissuesmost responsive to modulation of the androgen activity, this model isused to determine the androgen dependent growth of the sex accessoryorgans in immature castrated rats.

Male immature rats (19-20 days old Sprague-Dawley, HarlanSprague-Dawely) were castrated under metofane ansestesia. Five daysafter surgery these castrated rats (60-70 g, 23-25 day-old) were dosedfor 3 days. Animals were dosed sub-cutaneously (s.c.) 1 mg/kg withTestosterone Proprionate (TP) in arachis oil vehicle and anti-androgentest compounds (compounds of the present invention) were dosed orally bygavage (p.o.) in dissolved/suspensions of 80% PEG 400 and 20% Tween 80(PEGTW). Animals were dosed (v/w) at 0.5 ml of vehicle/100 g bodyweight. Experimental groups were as follows:

-   -   1. Control vehicle    -   2. Testosterone Propionate (TP) (3 mg/rat/day, subcutaneous)    -   3. TP plus Casodex (administered p.o. in PEGTW, QD), a        recognized antiandrogen, as a reference compound.    -   4. To demonstrate antagonist activity, a compound of the present        invention (“test compound”) was administered (p.o. in PEGTW, QD)        with TP (s.c. as administered in group 2) in a range of doses.    -   5. To demonstrate agonist activity a compound of the present        invention (“test compound”) was administered alone (p.o. in        PEGTW, QD) in a range of doses.

At the end of the 3-day treatment, the animals were sacrificed, and theventral prostate weighed. To compare data from different experiments,the sexual organs weights were first standardized as mg per 100 g ofbody weight, and the increase in organ weight induced by TP wasconsidered as the maximum increase (100%). ANOVA followed by one-tailedStudent or Fischer's exact test was used for statistical analysis.

The gain and loss of sexual organ weight reflect the changes of the cellnumber (DNA content) and cell mass (protein content), depending upon theserum androgen concentration. See Y. Okuda et al., J. Urol., 145,188-191 (1991), the disclosure of which is herein incorporated byreference. Therefore, measurement of organ wet weight is sufficient toindicate the bioactivity of androgens and androgen antagonist. Inimmature castrated rats, replacement of exogenous androgens increasesseminal vesicles (SV) and the ventral prostate (VP) in a dose dependentmanner.

The maximum increase in organ weight was 4 to 5-fold when dosing 3mg/rat/day of testosterone (T) or 1 mg/rat/day of testosteronepropionate (TP) for 3 days. The EC₅₀ of T and TP were about 1 mg and0.03 mg, respectively. The increase in the weight of the VP and SV alsocorrelated with the increase in the serum T and DHT concentration.Although administration of T showed 5-times higher serum concentrationsof T and DHT at 2 hours after subcutaneous injection than that of TP,thereafter, these high levels declined very rapidly. In contrast, theserum concentrations of T and DHT in TP-treated animals were fairlyconsistent during the 24 hours, and therefore, TP showed about10-30-fold higher potency than free T.

In this immature castrated rat model, a known AR antagonist (Casodex)was also administered simultaneously with 0.1 mg of TP (ED₈₀),inhibiting the testosterone-mediated increase in the weights of the VPand SV in a dose dependent manner. The antagonist effects were similarwhen dosing orally or subcutaneously. Compounds of the invention alsoexhibited AR antagonist activity by suppressing thetestosterone-mediated increase in the weights of VP and SV.

Levator Ani & Wet Prostate Weight Assay AR Agonist Assay:

The activity of compounds of the present invention as AR agonists wasinvestigated in an immature male rat model, a recognized test ofanabolic effects in muscle and sustaining effects in sex organs for agiven compound, as described in L. G. Hershberger et al., Proc. Soc.Expt. Biol. Med., 83, 175 (1953); B. L. Beyler et al, “Methods forevaluating anabolic and catabolic agents in laboratory animals”, J.Amer. Med. Women's Ass., 23, 708 (1968); H. Fukuda et al.,“Investigations of the levator ani muscle as an anabolic steroid assay”,Nago Dai. Yak. Ken. Nem. 14, 84 (1966) the disclosures of which areherein incorporated by reference.

The basis of this assay lies in the well-defined action of androgenicagents on the maintenance and growth of muscle tissues and sexualaccessory organs in animals and man. Androgenic steroids, such astestosterone (T), have been well characterized for their ability tomaintain muscle mass. Treatment of animals or humans after castrationswith an exogenous source of T results in a reversal of muscular atrophy.The effects of T on muscular atrophy in the rat levator ani muscle havebeen well characterized. M. Masuoka et al., “Constant cell population innormal, testosterone deprived and testosterone stimulated levator animuscles” Am. J. Anat. 119, 263 (1966); Z. Gori et al., “Testosteronehypertrophy of levator ani muscle of castrated rats. I. Quantitativedata” Boll.—Soc. Ital. Biol. Sper. 42, 1596 (1966); Z. Gori et al.,“Testosterone hypertrophy of levator ani muscle of castrated rats. II.Electron-microscopic observations” Boll.—Soc. Ital. Biol. Sper. 42, 1600(1966); A. Boris et al., Steroids 15, 61 (1970). As described above, theeffects of androgens on maintenance of male sexual accessory organs,such as the prostate and seminal vesicles, is well described. Castrationresults in rapid involution and atrophy of the prostate and seminalvesicles. This effect can be reversed by exogenous addition ofandrogens. Since both the levator ani muscle and the male sex organs arethe tissues most responsive to the effects of androgenic agents, thismodel is used to determine the androgen dependent reversal of atrophy inthe levator ani muscle and the sex accessory organs in immaturecastrated rats. Sexually mature rats (200-250 g, 6-8 weeks-old,Sprague-Dawley, Harlan) were acquired castrated from the vendor(Taconic). The rats were divided into groups and treated daily for 7 to14 days with one of the following:

-   -   1. Control vehicle    -   2. Testosterone Propionate (TP) (3 mg/rat/day, subcutaneous)    -   3. TP plus Casodex (administered p.o. in PEGTW, QD), a        recognized antiandrogen, as a reference compound.    -   4. To demonstrate antagonist activity, a compound of the present        invention (“test compound”) was administered (p.o. in PEGTW, QD)        with TP (s.c. as administered in group 2) in a range of doses.    -   5. To demonstrate agonist activity a compound of the present        invention (“test compound”) was administered alone (p.o. in        PEGTW, QD) in a range of doses.

At the end of the 7-14-day treatment, the animals were sacrificed bycarbon dioxide, and the levator ani, seminal vesicle and ventralprostate weighed. To compare data from different experiments, thelevator ani muscle and sexual organ weights were first standardized asmg per 100 g of body weight, and the increase in organ weight induced byTP was considered as the maximum increase (100%). Super-anova (onefactor) was used for statistical analysis.

The gain and loss of sexual organ weight reflect the changes of the cellnumber (DNA content) and cell mass (protein content), depending upon theserum androgen concentration. See Y. Okuda et al., J. Urol., 145,188-191 (1991), the disclosure of which is herein incorporated byreference. Therefore, measurement of organ wet weight is sufficient toindicate the bioactivity of androgens and androgen antagonist. Inimmature castrated rats, replacement of exogenous androgens increaseslevator ani, seminal vesicles (SV) and prostate in a dose dependentmanner.

The maximum increase in organ weight was 4 to 5-fold when dosing 3mg/rat/day of testosterone (T) or 1 mg/rat/day of testosteronepropionate (TP) for 3 days. The EC₅₀ of T and TP were about 1 mg and0.03 mg, respectively. The increase in the weight of the VP and SV alsocorrelated with the increase in the serum T and DHT concentration.Although administration of T showed 5-times higher serum concentrationsof T and DHT at 2 hours after subcutaneous injection than that of TP,thereafter, these high levels declined very rapidly. In contrast, theserum concentrations of T and DHT in TP-treated animals were fairlyconsistent during the 24 hours, and therefore, TP showed about10-30-fold higher potency than free T.

MDA PCa2b Human Prostate Zenograft Assay:

In Vivo Antitumor Testing: MDA-PCa-2b human prostate tumors weremaintained in Balb/c nu/nu nude mice. Tumors were propagated assubcutaneous transplants in adult male nude mice (4-6 weeks old) usingtumor fragments obtained from donor mice. Tumor passage occurred every5-6 weeks.

For antitumor efficacy trial, the required number of animals needed todetect a meaningful response were pooled at the start of the experimentand each was given a subcutaneous implant of a tumor fragment (˜50 mg)with a 13-gauge trocar. Tumors were allowed to grow to approx. 100-200mg (tumors outside the range were excluded) and animals were evenlydistributed to various treatment and control groups. Treatment of eachanimal was based on individual body weight. Treated animals were checkeddaily for treatment related toxicity/mortality. Each group of animalswas weighed before the initiation of treatment (Wt1) and then againfollowing the last treatment dose (Wt2). The difference in body weight(Wt2−Wt1) provides a measure of treatment-related toxicity.

Tumor response was determined by measurement of tumors with a calipertwice a week, until the tumors reach a predetermined “target” size of0.5 gm. Tumor weights (mg) were estimated from the formula: Tumorweight=(length×width2)÷2

Tumor response end-point was expressed in terms of tumor growthinhibition (% T/C), defined as the ratio of median tumor weights of thetreated tumors (T) to that of the control group (C).

To estimate tumor cell kill, the tumor volume doubling time was firstcalculated with the formula:TVDT=Median time (days) for control tumors to reach target size−Mediantime (days) for control tumors to reach half the target size s And, Logcell kill=(T−C)÷(3.32×TVDT)

Statistical evaluations of data were performed using Gehan's generalizedWilcoxon test.

Dunning Prostate Tumor:

Dunning R3327H prostate tumor is a spontaneously derived, welldifferentiated androgen responsive adenocarcinoma of the prostate(Smolev J K, Heston W D, Scott W W, and Coffey D S, Cancer Treat Rep.61, 273-287 (1977)). The growth of the R3327H subline has been selectedfor its highly androgen-dependent and reproducible growth in intact malerats. Therefore, this model and other sublines of this tumor have beenwidely used to evaluate in vivo antitumor activities of antiandrogenssuch as flutamide and bacilutamide/Casodex (Maucher A., and von Angerer,J. Cancer Res. Clin. Oncol., 119, 669-674 (1993), Furr B. J. A. Euro.URL. 18 (suppl. 3), 2-9 (1990), Shain S. A. and Huot R I. J. SteriodBiochem. 31, 711-718 (1988)).

At the beginning of the study, the Dunning tumor pieces (about 4×4 mm)are transplanted subcutaneously to the flank of mature male Copenhagenrats (6-7 weeks old, Harlan-Sprague Dawley, Indianapolis, Md.). About 6weeks after the implantation, the animals with tumors of measurable size(about 80-120 mm²) are randomized into treatment groups (8-10rats/group) and the treatments are initiated. One group of the rats arecastrated to serve as the negative control of tumor growth. Animals aretreated daily with compounds of the current invention, standardantiandrogens such as bacilutamide or vehicle (control) for an averageof 10 to 14 weeks. Test compounds are dissolved in a vehicle of (2.5ml/kg of body weight) 10% polyethylene glycol and 0.05% Tween-80 in 1%carboxymethyl cellulose, PEG/CMC, (Sigma, St Louis, Mo.). Typicaltherapeutic experiments would include three groups of three escalatingdoses for each standard or test compound (in a range of 300-3 mg/kg).

Tumors in the vehicle (control) group reach a size of 1500 to 2500 mm³,whereas the castrated animal group typically shows tumor stasis over the14 weeks of observation. Animals treated orally with 20 mg/kg ofbicalutamide or flutamide would be expected to show a 40% reduction intumor volumes compared to control after 14 weeks of treatment. The sizeof tumors are measured weekly by vernier caliper (Froboz, Switzerland),taking perpendicular measurements of length and width. Tumor volumes aremeasured in mm³ using the formula: Length×Width×Height=Volume.Statistical differences between treatment groups and control areevaluated using multiple ANOVA analysis followed by one tailnon-parametric Student t test.

Mature Rat Prostate Weight Assay:

The activity of compounds of the present invention were investigated ina mature male rat model, which is a variation of the Levator ani & wetprostate weight assay described above. The above in vivo assays arerecognized assays for determining the anabolic effects in muscle andsustaining effects in sex organs for a given compound, as described inL. G. Hershberger et al., 83 Proc. Soc. Expt. Biol. Med., 175 (1953); B.L. Beyler et al, “Methods for evaluating anabolic and catabolic agentsin laboratory animals”, 23 J. Amer. Med. Women's Ass., 708 (1968); H.Fukuda et al., “Investigations of the levator ani muscle as an anabolicsteroid assay”, 14 Nago Dai. Yak. Ken. Nem. 84 (1966) the disclosures ofwhich are herein incorporated by reference. The basis of this assay liesin the well-defined action of androgenic agents on the maintenance andgrowth of muscle tissues and sexual accessory organs in animals and man.

The male sexual accessory organs, such as the prostate and seminalvesicles, play an important role in reproductive function. These glandsare stimulated to grow and are maintained in size and secretory functionby the continued presence of serum testosterone (T), which is the majorserum androgen (>95%) produced by the Leydig cells in the testis underthe control of the pituitary luteinizing hormone (LH) and folliclestimulating hormone (FSH). Testosterone is converted to the more activeform, dihydrotestosterone, (DHT), within the prostate by 5α-reductase.Adrenal androgens also contribute about 20% of total DHT in the ratprostate, compared to 40% of that in 65-year-old men. F. Labrie et.al.16 Clin. Invest. Med., 475-492 (1993). However, this is not a majorpathway, since in both animals and humans, castration leads to almostcomplete involution of the prostate and seminal vesicles withoutconcomitant adrenalectomy. Therefore, under normal conditions, theadrenals do not support significant growth of prostate tissues, M. C.Luke and D. S. Coffey, “The Physiology of Reproduction” ed. By E. Knobiland J. D. Neill, 1, 1435-1487 (1994). Since the male sex organs and thelevator ani are the tissues most responsive to modulation of theandrogen activity, this model is used to determine the activity ofcompounds that modulate the androgen receptor pathway in mature rats.

Along with its mitogenic activity on tissues such as prostate, seminalvesicle and muscle, testosterone also serves as a negative regulator forits own biosynthesis. Testosterone production in the Leydig cells of thetestis is controlled by the level of circulating LH released from thepituitary gland. LH levels are themselves controlled by the level ofLHRH produced in the hypothalmic region. Testosterone levels in theblood serve to inhibit the secretion of LHRH and subsequently reducelevels of LH and ultimately the levels of circulating testosteronelevels. By measuring blood levels of LH as they are effected bycompounds of the present invention (“test compounds”), it is possible todetermine the level of agonist or antagonist activity of said compoundsat the hypothalamic axis of this endocrine cycle.

Matched sets of Harlan Sprague-Dawely rats (40-42 days old, 180-220 g),were dosed orally by gavage (p.o.) with the test compounds indissolved/suspensions of 80% PEG 400 and 20% Tween 20 (PEGTW) for 14days. Two control groups, one intact and one castrated were dose orallyonly with the PEGTW vehicle. Animals were dosed (v/w) at 0.5 ml ofvehicle/100 g body weight. Experimental groups were as follows:

-   -   1. Intact vehicle (p.o., PEGTW, QD)    -   2. Control vehicle (p.o., PEGTW, QD)    -   3. Bicalutamide (Casodex, a recognized antiandrogen, as a        reference compound) or a compound of the present invention, p.o.        in PEGTW QD. (in a range of doses). At the end of the 14-day        treatment, the animals were sacrificed, and the ventral        prostate, the seminal vesicles, and the levator ani were removed        surgically and weighed. To compare data from different        experiments, the organs weights were first standardized as mg        per 100 g of body weight, and expressed as a percentage of the        value of the respective organ in the intact group.

Rat luteinizing hormone (rLH) is quantitatively determined with theBiotrak [125 I] kit (Amersham Pharmacia Biotek), following themanufacturer directions. The assay is based on the competition by the LHpresent in the serum of the binding of [¹²⁵I]0 rLH to an Amerlex-Mbead/antibody suspension. The radioactivity that remains afterincubation with the serum and subsequent washes is extrapolated into astandard curve to obtain a reading in ng/ml.

The gain and loss of sexual organ and levator ani weight reflect thechanges of the cell number (DNA content) and cell mass (proteincontent), depending upon the serum androgen concentration, see Y. Okudaet al., J. Urol., 145, 188-191 (1991), the disclosure of which in hereinincorporated by reference. Therefore, measurement of organ wet weight issufficient to indicate the bioactivity of androgens and androgenantagonist. In the mature rats assay, active agonist agents will have noeffect or will increase the weight of one or more of the androgenresponsive organs (levator ani, prostate, seminal vessicle) and willhave no effect or a suppressive effect on LH secretion. Compounds withantagonist activity will decrease the weight of one or more of theandrogen responsive organs (levator ani, prostate, seminal vesicle) andwill have no effect or a reduced suppressive effect on LH secretion.

CWR22 Human Prostate Zenograft Assay:

In Vivo Antitumor Testing: CWR22 human prostate tumors were maintainedin Balb/c nu/nu nude mice. Tumors were propagated as subcutaneoustransplants in adult male nude mice (4-6 weeks old) using tumorfragments obtained from donor mice. Tumor passage occurred every 5-6weeks.

For antitumor efficacy trial, the required number of animals needed todetect a meaningful response were pooled at the start of the experimentand each was given a subcutaneous implant of a tumor fragment (˜50 mg)with a 13-gauge trocar. Tumors were allowed to grow to approx. 100-200mg (tumors outside the range were excluded) and animals were evenlydistributed to various treatment and control groups. Treatment of eachanimal was based on individual body weight. Treated animals were checkeddaily for treatment related toxicity/mortality. Each group of animalswas weighed before the initiation of treatment (Wt1) and then againfollowing the last treatment dose (Wt2). The difference in body weight(Wt2-Wt1) provides a measure of treatment-related toxicity.

Tumor response was determined by measurement of tumors with a calipertwice a week, until the tumors reach a predetermined “target” size of0.5 gm. Tumor weights (mg) were estimated from the formula: Tumorweight=(length×width2)÷2.

Tumor response end-point was expressed in terms of tumor growthinhibition (% T/C), defined as the ratio of median tumor weights of thetreated tumors (T) to that of the control group (C).

To estimate tumor cell kill, the tumor volume doubling time was firstcalculated with the formula:TVDT=Median time (days) for control tumors to reach target size−Mediantime (days) for control tumors to reach half the target size And, Logcell kill=(T−C)÷(3.32×TVDT)

Statistical evaluations of data were performed using Gehan's generalizedWilcoxon test.

The mixture turned into a yellow gel and was vigorouslyshaken (wrist action shaker for 4 h.). All the solvents were absorbed bythe resin and it looked dry. The resin was washed in portions withCH₂Cl₂ (200 mL) and the washes were combined and extracted with 200 mL1N HCl. The HCl fraction was re-extracted with ethyl acetate (200 mL).The organic fractions were combined and extracted with water (50 mL),brine (50 mL) and the organic fractions were dried over sodium sulfate,filtered and concentrated to give 2.1 g of resin bound compound 496A(89% loaded based on recovered unbound compound 495Ai). The resin waswashed consecutively with DMF (5×), DMF: water (3:1, 5×), THF (3×) andCH₂Cl₂ (3×) (˜30 mL each wash). The resin was dried in vacuo for 1 h toyield 5.35 g of resin. The resin was still wet and was re-treated withthe alcohol. The above described loading process was repeated using therecovered un-reacted compound 495Ai from the above procedure. Recoveredcompound 495Ai (2.1 g, 5.6 mmol) and anhydrous dichloromethane (15 mL)and pyridine (15 mL) and the resin were combined and subjected to thereaction conditions described above. The resulting resin was washed asdescribed previously and dried in vacuo overnight to yield 4.49 g ofresin (87% loaded based on recovered unbound compound 495Ai). Thestarting alcohol was recovered from the dichloromethane:pyridine mixtureas described previously (2.04 g of white solid, which would suggest a92% loading based on recovered alcohol). The resin weigh increase isusually more accurate for loading assessment. The resin loading wascalculated to be 0.87 (determined by resin weight increase)×1.08 mmol/g(calculated 100% loading)=0.94 mmol/g. The resin was used as is for thenext step.

The following procedure describes a general process by which arrays ofcompounds of Formula I can be made using automated approaches.Additional information on such automated synthetic approaches can befound in Example 8. Compounds 496Bi & 496Bii are an example of compoundsmade by such a procedure. For compounds 496Bi & 496Bii,4-chloropyridinol represents the nuceophile reagent. A broaderdefinition of the term nucleophile is contained in the body of thisdocument and is well understood by one skilled in the art. A BohdanMiniReactor equipped with a heating/cooling block was used with 0.5 Dramvials stacked over one another to achieve the same level as the reactortubes. Resin (compound 496A) was measured into the individual vials byusing each Bohdan resin Transfer module plate “10 mg” and “20 mg” once.The weights of resin delivered ranged from 17-23 mg (0.016-0.022 mmol).Cesium carbonate was added using the Bohdan “20 mg” plate whichdelivered ˜57-60 mg (0.17-0.18 mmol). The nucleophiles were weightedinto 1 Dram vials and were diluted in THF to 0.06 M using a Tecan eightchannel liquid handler. The resulting solutions (250 μL, 0.015 mmol)were added manually via a micro-pipette to each of the reaction vialscontaining resin and the resulting array of reaction vials were placedin a Bohdan reactor. When the nucleophiles are amines, ˜13 μL ofdiisopropylethylamine was added to the THF solution of the amine. Thevials were capped (Teflon-lined) and the reactions were heated withorbital shaking (short stroke 500 rpm) at 70° C. for 24 h. The reactionswere cooled to 25° C. and 1 mL of a mixture of heptane and ethyl acetate(1:1) was added followed by 0.5 mL of water. The organic layer wasextracted manually and individually transferred to a synthesis blocktube containing magnesium sulfate (˜150 mg). The array of synthesisblock tubes were simultaneously filtered and the filtrates wereindividually collected into microtubes (96 well block). The aqueouslayer was re-extracted with 1 mL of a mixture of heptane and ethylacetate (1:1), the organic layer was filtered as described above and thefiltrate was individually collected as described above into the existingmicrotubes.

Analysis of the array of compounds prepared by the above procedure wasperformed using the following automated approach. A 120 W portion ofeach of the above reaction (filtrates) was aliquoted into two 96 deepwell blocks for analysis. The solvent was concentrated in vacuo and theplates were re-diluted with methanol (500 μL).

Microbial transformation of compound 472 to compound 515 was conductedon a 3 L scale in a 5 L fermentor, using Cunninghamella echinulata SC16027 (ATCC 9244) and a medium consisting of the following: 0.5% toastednutrisoy, 2% glucose, 0.5% yeast extract, 0.5% K₂HPO₄, 0.5% NaCl,adjusted to pH 7 with 1N HCl (R. V. Smith and J. P. Rosazza, Arch.Biochem. Biophys., 161, 551-558 (1974)). The fermentor was batched with0.05% SAG antifoam before sterilization. Spore inoculum was prepared bywashing the spores from a 10 day slant culture of Cunninghamellaechinulata SC 16027 (ATCC 9244) with 0.9% saline/0.1% Tween 80. Theinoculum stage was prepared by adding 1 mL of spore inoculum into 100 mLmedium in a 500 mL flask, then the cultures were grown at 28° C. at 200rpm for 1 day. 10% inoculum from the flask was blended in a sterileWaring blender and used to inoculate the sterile fermentor, containing 3L of sterile media. The fermentor was run at 28° C. at 600 rpm and 1 vvmaeration. A sterile solution of three antibiotics was added to thefermentor after inoculation; 12 mg of tetracycline chloride, 12 mg ofkanamycin sulfate, and 60 mg of cephalexin hydrate in 10 mL of deionizedwater. After 22 hours of growth in the fermentor, a sterile substratesolution was added containing 0.75 g of compound 472 dissolved in 30 mLof methanol, this step was repeated two hours later for a total of 0.5g/L of compound 472 in the bioconversion.

EXAMPLES 879 TO 1020

Additional compounds of the present invention were prepared byprocedures analogous to those described above. The compounds of Examples879 to 1020 have the following structure (L is a bond):

-   -   where the structure, the compound name, retention time,        molecular mass, and the procedure employed, are set forth in        Table 18. The absolute configuration for designated compounds        was not determined. Compounds having one or more optical centers        are designated as being racemic or chiral. Racemic compounds        represent a mixture of both possible antipodes. Chiral refers to        a compound, which represents a single antipode of a possible        pair. For compounds that are chiral but the absolute        stereochemistry is not known, the structure does not reflect the        absolute stereochemistry. For compounds which are chrial and the        absolute stereochemistry is known by reference to a starting        material, then the structure drawn reflects the absolute        stereochemistry of the compound.
